This medication is given by injection into the buttock muscle by a health care professional as directed by your doctor, usually every 2 to 4 weeks. Do not rub/massage the injection site after your dose. Do not inject into a vein or under the skin.
Dosage is based on your medical condition and response to treatment.
Use this medication regularly to get the most benefit from it. To help you remember, mark the days on the calendar when you need to receive the medication.
Tell your doctor if your condition lasts or gets worse.
Drowsiness, dizziness, lightheadedness, nausea, constipation, increased appetite, weight gain, dry mouth, headache, or redness/pain/swelling at the injection site may occur. If any of these effects last or get worse, notify your doctor or pharmacist promptly.
Dizziness and lightheadedness can increase the risk of falling. Get up slowly when rising from a sitting or lying position.

Olanzapine extended-release injection is designed to release medication slowly over 2 to 4 weeks. If the medication releases too quickly, your drug levels may be too high.
